Our knowledge about the neurobiological correlates of positive visual perceptual disorders is increasing rapidly. If we are to understand and integrate this emerging knowledge, the nomenclature needs to be clear and unambiguous.
To provide an overview of the different classifications of visual hallucinations to reach a better understanding of new neurobiological views in these phenomena.
Relevant data were obtained from books, PubMed, Embase, and the Cochrane Library.
The results are presented in the form of various classifications of visual hallucinations, grouped according to the following guiding principles: shape, size, content, relation to the sleepwake cycle, co-occurrence with percepts in any of the other sensory modalities, and association with neurobiological correlates. In addition, a classification system for visual illusions and distortions is presented.
The overview emphasizes how important it is to reappraise the concepts of positive visual perceptual disorders that were developed during the era of classical psychiatry. By becoming familiar with these concepts we will find it easier to design, execute and interpret neurobiological studies of these frequently occurring phenomena.
我们对阳性视觉感知障碍的神经生物学相关性的认识正在迅速增加。如果我们要理解并整合这些新出现的知识，术语需要清晰明确。
概述视觉幻觉的不同分类，以便更好地理解这些现象中的新神经生物学观点。
相关数据来自书籍、PubMed、Embase和Cochrane图书馆。
结果以视觉幻觉的各种分类形式呈现，根据以下指导原则分组：形状、大小、内容、与睡眠-觉醒周期的关系、与任何其他感觉模态中的感知同时出现，以及与神经生物学相关性。此外，还提出了视觉错觉和变形的分类系统。
该概述强调了重新评估经典精神病学时代发展起来的阳性视觉感知障碍概念的重要性。通过熟悉这些概念，我们将更容易设计、实施和解释对这些常见现象的神经生物学研究。
